If you are trying to get a Root Cause issue using blame, don’t forget use the -w flag to ignore all the white-spaces or indentation changes. So you’ll get the last real change to the code, instead just an indentation, or removing trailing spaces. git blame -w app/to/file.rb or you can just use, git slap … Read more
If you are more interested in the bits that are not whitespace, you can match the non-whitespace instead of splitting on whitespace. ” The quick brown fox jumps over the lazy dog. “.match(/\S+/g); Note that the following returns null: ” “.match(/\S+/g) So the best pattern to learn is: str.match(/\S+/g) || []
Add vertical-align: top to textarea. The reason for the gap is that textarea is an inline (or inline-block) element, and the gap is the space reserved for descenders in text. I don’t know exactly why the gap is different between different browsers.
You’re looking for TRIM. UPDATE FOO set FIELD2 = TRIM(FIELD2); Seems like it might be worth it to mention that TRIM can support multiple types of whitespace, but only one at a time and it will use a space by default. You can, however, nest TRIMs. TRIM(BOTH ‘ ‘ FROM TRIM(BOTH ‘\n’ FROM column)) If … Read more
String.Trim() returns a string which equals the input string with all white-spaces trimmed from start and end: ” A String “.Trim() -> “A String” String.TrimStart() returns a string with white-spaces trimmed from the start: ” A String “.TrimStart() -> “A String ” String.TrimEnd() returns a string with white-spaces trimmed from the end: ” A String … Read more
See the String method trim() – https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/Trim var myString = ‘ bunch of <br> string data with<p>trailing</p> and leading space ‘; myString = myString.trim(); // or myString = String.trim(myString); Edit As noted in other comments, it is possible to use the regex approach. The trim method is effectively just an alias for a regex: if(!String.prototype.trim) … Read more
A simple possibility (if you’d rather avoid REs) is ‘ ‘.join(mystring.split()) The split and join perform the task you’re explicitly asking about — plus, they also do the extra one that you don’t talk about but is seen in your example, removing trailing spaces;-).
Add a \s? if a space can be allowed. \s stands for white space ? says the preceding character may occur once or not occur. If more than one spaces are allowed and is optional, use \s*. * says preceding character can occur zero or more times. ‘#<a href\s?=”https://stackoverflow.com/questions/14293024/(.*?)” title\s?=”https://stackoverflow.com/questions/14293024/(.*?)”><img alt\s?=”https://stackoverflow.com/questions/14293024/(.*?)” src\s?=”https://stackoverflow.com/questions/14293024/(.*?)”[\s*]width\s?=”150″[\s*]height\s?=”https://stackoverflow.com/questions/14293024/(.*?)”></a>#’ allows an optional … Read more
This is fastest way I know of, even though you said you didn’t want to use regular expressions: Regex.Replace(XML, @”\s+”, “”); Crediting @hypehuman in the comments, if you plan to do this more than once, create and store a Regex instance. This will save the overhead of constructing it every time, which is more expensive … Read more
As of R 3.2.0 a new function was introduced for removing leading/trailing white spaces: trimws() See: Remove Leading/Trailing Whitespace
